This can sometimes be caused by the script terminating before it outputs the header, meaning a runtime error in the script: are you using '-w', use 'strict'; ? these should highlight any errors not necessarily related to syntax Another consideration is that on most servers, due to security issues that can arise from running CGIs, users usually have to put their cgis in a specific directory. In other words you can't just upload your cgi to just anywhere in your user account, and then call it from a web browser. A simple way to check either of these is to telnet to your account and run the cgi from the command line and see what you get in terms of a response. You can get loads more pointers of where and what to look for from these links: <<From POD FAQ Networking (FAQ9) CGI FAQ http://www.webthing.com/tutorials/cgifaq.html Web FAQ http://www.boutell.com/faq/ WWW Security FAQ http://www.w3.org/Security/Faq/ HTTP Spec http://www.w3.org/pub/WWW/Protocols/HTTP/ HTML Spec http://www.w3.org/TR/REC-html40/ http://www.w3.org/pub/WWW/MarkUp/ CGI Spec http://www.w3.org/CGI/ CGI Security FAQ http://www.go2net.com/people/paulp/cgi-security/safe-cgi.txt >From POD FAQ Networking>> I'd highly recommend reading through all of these to make sure you're familiar with cgis.
